AccessViolationException in optimize operation

[chavas]

Hi,

I get 'AccessViolationException' in optimize operation when optimizing a 200mb file. This exception crashes my application. Here is the code that I wrote-
Function PDFOptimize_stream(ByRef _memstream As MemoryStream, ByRef _memstream1 As MemoryStream, ByRef m_Inst As PDFXEdit.PXV_Inst, ByRef m_pxcInst As PDFXEdit.IPXC_Inst) As Integer
Dim srcIStream As IStreamWrapper = New IStreamWrapper(_memstream)
Dim srcIStream1 As IStreamWrapper = New IStreamWrapper(_memstream1)
Dim nID As Integer = m_Inst.Str2ID("op.document.optimize", False)
Dim op As PDFXEdit.IOperation = m_Inst.CreateOp(nID)
Dim input As PDFXEdit.ICabNode = op.Params.Root("Input")
Dim pxcInst As PDFXEdit.IPXC_Inst = CType(m_Inst.GetExtension("PXC"), PDFXEdit.IPXC_Inst)
Dim resDoc As PDFXEdit.IPXC_Document = pxcInst.OpenDocumentFrom(srcIStream, Nothing)
input.Add().v = resDoc
Dim options As PDFXEdit.ICabNode = op.Params.Root("Options")
Dim images As PDFXEdit.ICabNode = options("Images")
images("Enabled").v = True
images("ReducedOnly").v = True
Dim comp As PDFXEdit.ICabNode = images("Comp")
comp("Color.JPEGQuality").v = 1
comp("Grayscale.JPEGQuality").v = 0
op.Do()
resDoc.WriteTo(srcIStream1, Nothing, 1)
resDoc.Close()
srcIStream = Nothing
end function

I am passing memorystream to this function which contains the source file and after optimizing, I save it in the second memory stream.
I get exception in 'op.do' . This does not happen immediately, but after some time of calling 'op.do'.

Hello Charu,

We will need the exception details, and also the version of the dll that you are using.

Cheers,
